用植物提取物配制水性涂料及涂层形貌

为了对植物果实、叶子和表皮等资源的深加工利用，本文利用植物提取物多羟基酚酸和磷酸为主要转化剂，通过正交试验优化研制成一种无毒快干，具有化锈、防锈、耐腐蚀性能的新型锈面涂料。用来对钢铁油漆前的表面处理。采用传统的腐蚀性能评价方法测定涂料的耐腐蚀性能，并使用SEM扫描电镜观察了涂层的形貌。结果表明该涂料具有较好的带锈涂装性，对密锈层100μm以下的钢铁表面不经过除锈、喷砂等传统的十几道处理工序，而是直接涂装，收到满意效果。涂料具有很强的化锈能力和腐蚀防护性能，具有极大的科研开发价值、经济价值和社会效益。

Rusted coating with plant extracts and its morphology

In order to make use of fruits, cortexes and leaves of plants, a novel quick-drying, nontoxic and corrosion-inhibiting daub for rusted steel protection, containing polyphenol carboxyl acid and phosphorous acid as main rust converter, was developed through orthogonal test optimization, and applied to the rusted surface treatment before painting. The protection ability of the rusted coating was evaluated, and the coating morphology was observed through SEM. The results confirm that the rusted coating can effectively convert rust and protect the steel substrate.
